What this calculator helps you do
Estimate a level monthly payment for a personal, auto, education, equipment, or other installment loan. The calculation runs entirely in your browser; SENNA Finance does not receive the values entered into this tool.
Worked example
Using the default example—loan amount of $25,000, annual interest rate of 9.5%, repayment term of 60 months, upfront fees of $0—the calculator returns monthly payment of $525.05; total interest: $6,502.79; upfront fees: $0.00. Change the assumptions to match your own case rather than relying on the example.
Formula and calculation basis
Inputs are converted to the periodic units required by the formula. Results are calculated with full JavaScript numeric precision and rounded only for display.
How to interpret the result
Compare the payment with the total borrowing cost. A manageable monthly payment can hide substantial interest when the term is extended.
Common mistakes to avoid
- Leaving origination fees out of the comparison.
- Comparing payments across loans with different terms without checking total cost.
- Using an annual rate that already includes fees as if it were the nominal interest rate.
Limits and assumptions
The calculation assumes equal monthly payments and a fixed rate. It excludes irregular payments, changing rates, taxes, insurance, and late charges.
Outputs are estimates, not contractual quotations, regulated disclosures, tax advice, investment advice, or a substitute for professional review.
Frequently asked questions
Is this the same as an EMI calculator?
Yes. For a standard reducing-balance installment loan, the monthly payment is the equated monthly installment.
What happens when the rate is zero?
The principal is divided evenly across the entered number of months.
Are fees included in the monthly payment?
The displayed payment is based on principal and interest. Fees are included separately in total borrowing cost.
